Figure 13. Writing Design Status
After CBPro writes the default plan to the EVB, click on “Open EVB GUI” as shown below.
Figure 14. Open EVB GUI
The EVB GUI will appear. Note all power supplies will be set to the values defined in the device’s default CBPro
project file created by Silicon Labs, as shown below.

10.5.1. Verify Free-Run Mode Operation
Assuming no external clocks have been connected to the INPUT CLOCK differential SMA connectors (labeled
“INx/INxB”) located around the perimeter of the EVB, the DUT should now be operating in free-run mode, as the
DUT will be locked to the crystal in this case.
You can run a quick check to determine if the device is powered up and generating output clocks (and consuming
power) by clicking on the Read All button highlighted above and then reviewing the voltage, current and power
readings for each VDDx supply.
Note: Shutting “Off” then “On” of the VDD and VDDA supplies will power-down and reset the DUT. Every time you do
this, to reload the Silicon Labs-created default plan into the DUT’s register space, you must go back to the Wiz-
ard’s main menu and select “Write Design to EVB”:
